Abstract: Disclosed is a semiconductor structure including at least one bipolar junction transistor (BJT), which is uniquely configured so that fabrication of the BJT can be readily integrated with fabrication of complementary metal oxide semiconductor (CMOS) devices on an advanced silicon-on-insulator (SOI) wafer. The BJT has an emitter, a base, and a collector laid out horizontally across an insulator layer and physically separated. Extension regions extend laterally between the emitter and the base and between the base and the collector and are doped to provide junctions between the emitter and the base and between the base and the collector. Gate structures are on the extension regions. The emitter, base, and collector are contacted. Optionally, the gate structures and a substrate below the insulator layer are contacted and can be biased to optimize BJT performance. Optionally, the structure further includes one or more CMOS devices. Also disclosed is a method of forming the structure.

Abstract: The present disclosure relates to semiconductor structures and, more particularly, to gate controlled transistors and methods of manufacture. The structure includes: an emitter region; a collector region; base regions on opposing sides of the emitter region and the collector region; and a gate structure composed of a body region and leg regions, the body region being located between the base regions on opposing sides of the emitter region and the collector region, and the leg regions isolating the base regions from both the emitter region and the collector region.
